In the secont part of the 6 grade textbooks, students continue to build on the foundation set in 6A; this set has a heavy emphasis on algebra and arithmetic skills needed to progress to more advanced topics in the later books.

**Overview**

In algebra, fractions are introduced – students learn to correctly and efficiently add, subtract, multiply, and divide proper and improper fractions, along with mixed numbers. They explore applications of fractions to geometry and elementary data science, presenting and analyzing information given in tables, charts, and diagrams.

Students also begin to work with negative numbers and exponents. In further geometric study, they expand their knowledge on plane figures, adding circles and regular polygons to the mix. The books close with yearly review, reminding students just how far they have come..
